Poet John Wedgwood Clarke explores the Red River in Cornwall, a watercourse barely more than a stream that has been heavily polluted by centuries of tin mining. Now, this powerful symbol of Cornish identity, home to some very rare, beautiful and resilient species, is slowly showing signs of coming back to life.\n\nExtracts from John's poem, Red River at the A30 Culvert, reveal his mixed thoughts about the river's toxic legacy, but as he meets both those with a connection with the river's industrial past and who care for it today, he finds new hope for its future.
